WebMost stable ground-state molecules contain closed-shell electron configurations with a completely filled valence shell in which all molecular orbitals are doubly occupied or empty. Radicals, on the other hand, have an odd number of electrons and are therefore paramagnetic species. WebClosed shell is a term that describes one of the stages of building a house. It usually takes place shortly after reaching the open shell, including primarily the creation of the …
